Application September 4 Claims.

This invention relates to new and useful improvements in a safety clamp for holding the panes of glass of a show case together.

The invention has for an object the construction of a safety clamp which is characterized by a pair of adjacent members each comprising a channel portion for engagingthe top edge of a vertical pane of glass and a flange portion fixedly attached on said channel portion for engaging the edge of a top horizontal pane of glass.

Furthermore, the invention contemplates the forming of said members with their adjacent sides cut at 45 and joining with each other, and jointly forming a right angle clamp as Viewed in plan view, so as to be capable of engaging, for

example, the top corners of a glass show case.

Another one of the objects of this invention is the provision of means for holding the memb-ers releasably together.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features'of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:-'

The safety clip, according to this invention, comprises a pair of adjacent members Ill and Ill each comprising a channel portion II for engaging upon the top edge of a vertical pane 5 of glass l2 or l2 and a flange portion 13 fixedly ASES AND THE LIKE Wild, Flushing, N. Y., and Bernhardt dgefield, N. J.

padding material I6 is mounted on the flange 13.

These paddingmaterials are adapted to engage against the glass and keep the glass out of direct contact with the metal clip, thus lessening loss from breaking or chipping of thepanes of glass.

The flange portion l3 comprises a base section l3 which is soldered or in any other manner secured .to the channel portion H, and a vertical edge portion [3 which continues at right angles from the portion I3 A means is provided for holding the members HI and 10 together so that they may be separated and replaced when desired. This means comprises essentially a flat spring I8 attached by several rivets H] at one of its ends on the bottom of the flange portion l3 of one of the members W and extending across the flange portion of the other member, the member lo At the free end the spring I8 is provided with a peg 20 which engages a receiving opening 2| in themember l0.

Holding elements are also arranged upon the inner corner of the safety clamp and comprises among 22 stamped from the material II of one of the channel shaped members. This prong 22 is provided with a head 22 A loop element 23 is stamped from the face ll of the adjacent channel member. This loop has an open end portion 24 and a slot 25 in its front side. The arrangement is such that the head 22 may engage in the open end 24 and the prong portion 22 project out from the slot 25. The device is shown in this condition in Figs. 1 and 2.

The operation of the device is as follows:-

The spring l8 may be flexed to disengage the stud 20 from the opening 2|. Then the members Ill and lo may be pivoted around the prong 22 as a pivot and moved so that the head portion 22 passes out through the opening 24. Then the members It! and lo are separated. They may be joined by reengaging the parts.

In Fig. 6 a strip of material is shown from which the safety clip, according to this invention, may be constructed. This strip of material consists of an outer portion 21 having a horizontal central portion 21 an end portion 2'! turned at right angles downwards from the central portion, and another end portion 21 turned at right angles upwards from the central portion. An angle member 28 has one of its arms secured along the bottom of the center portion 21 and its other arm extending parallel to the end portion 21 Thus, the projecting of the arm of the angle and the adjacent portion 21 form a channel by which the strip may be engaged on the edge of a pane of glass. The upward extending portion 21 forms a flange for holding a horizontal pane of glass. The material as shown in Fig. 6 may be cut into pieces having side portions disposed at 45 from the length of the material. These angle portions may then be set together to form a corner piece as illustrated in Fig. '7. The adjacent edges of these angle portions may be soldered or brazed together.

In Figs. 8 and 9 a modification of the invention has been disclosed in which the safety clamp is adapted to be secured upon the side wall of a wooden show case. According to this form of the invention a lug portion 2'! is bent outwards from the end portion 21. This lug portion 21' is formed with an aperture 29 through which a headed screw may be engaged to attach the lug to the wooden side of a show case, as for example, the wooden portion 30. In other respects this form of the invention is similar to the preferred form and identical parts may be recognized by the same reference numerals.

While we have illustrated and described the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described our invention, what we claim as new, and desire to secure by United States Letters Patent is:-

1. A safety clamp comprising a pair of adjacent members each comprising a channel portion for engaging on the top edge of a vertical pane of glass and a flange portion fixedly attached on said channel portion for engaging the edge of a top horizontal pane of glass, and said members having adjacent sides cut at 45 and engaging each other and jointly forming a right angle clamp in plan view, and means for holding said members together, comprising an element formed from one of said portions and engaging in a receiving member formed from the other of said portions for holding one edge of said clamp together, a leaf spring fixedly mounted on one portion of said clamp, and a peg on said leaf spring engaging a receiving opening in the other portion of said clamp for holding the other edge of said clamp together.

2. A safety clamp comprising a pair of adjacent members each comprising a channel portion for engaging on the top edge of a vertical pane of glass and a flange portion fixedly attached on said channel portion for engaging the edge of a top horizontal pane of glass, and said members having adjacent sides cut at 45 and. engaging each other and jointly forming a right angle clamp in plan view, and means for holding said members together, including a spring element mounted on one member and supporting a peg engageable in a receiving opening in the other member.

3. A safety clamp comprising a pair of adjacent members each comprising a channel portion for engaging on the top edge of a vertical pane of glass and a flange portion fixedly attached on said channel portion for engaging the edge of a top horizontal pane of glass, and said members having adjacent sides cut at 45 and engaging each other and jointly forming a right angle clamp in plan view, and means for holding said members together, including a spring element mounted on one member and supporting a peg engageable in a receiving opening in the other member, and a prong stamped from the inner corner of said right angle clamp from one of the members thereof and engaging a receiving loop element formed from the adjacent member.

4. A safety clamp comprising a pair of adjacent members each comprising a channel portion for engaging on the top edge of a vertical pane of glass and a flange portion fixedly attached on said channel portion for engaging the edge of a top horizontal pane of glass, and said members having adjacent sides cut at 45 and engaging each other and jointly forming a right angle clamp in plan view, and means for holding said members together, including a spring element mounted on one member and supporting a peg engageable in a receiving opening in the other member, and a prong stamped from the inner corner of said right angle clamp from one of the members thereof and engaging a receiving loop element formed from the adjacent member, said loop element having an open end and a slot, said prong having a head engageable into said open end and a body portion extending from said slot.
